Patented Jan. 18, 1216.

Ap lication filed may 22, 1915. Serial No. 29,716.

To all whom it may concern Be it known that 1, Ivan Mnunnme, a. subject of the Crown of Sweden, residing at Brooklyn, county of Kings, and State of New York, have invented certain new and useful Tmpr vements in Apparatus for Cleaning Cotton, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to apparatus for cleaning cotton and its object is to improve the construction of such apparatus and to provide a structure which is simple and inexpensive to manufacture and to erect.

Another object is to so dispose the various parts of the apparatus that the extraneous matter which is removed from the cotton as it is cleaned, cannot clog or choke up the apparatus or become again mingled with the cleaned cotton.

T will describe my invention in the following specification and then point out the novel features thereof in appended claims.

Referring to the drawings: Figure 1 is a side elevation of a cotton cleaning apparatus which embodies myinvention. A por. tion of the same apparatus is shown on a larger scale in sectional side elevation in Fig. 2 and in sectional end elevation in Fig. 3.

Like characters of reference designate corresponding parts in'all the figures.

10 designates a base upon which the apparatus is supported. This may be made conveniently of channel irons as shown. Upon this are mounted a desired number of dust boxes 11. These are made of the same shape and dimensions and any desired number of them may be mounted on the base 10; in fact the number of the units formed by the dust boxes and the parts which are supported by them, may be added to or sub' tracted from at any time.

In the upper central portion of each dust box is a semi-circular plate 12 and spaced therefrom a concentric perforated plate or screen 13. These form between them a curved channel. 14L opposite which in the sides of the dust box are glass covered port holes 15. Below the screen 13 are openings covered by removable plates 16, by means of which access is obtainable to the inside of the dust box. It is also desirable to have the ports 15 openable for the purpose of providing means for cleaning the surfaces of the screens.

Supported on each dust box abovethe openings of the curved channel 1% are two casings 17 which form vertical chambers. The upper ends of these vertical casings are connected with similar ends of the nearest casing or the adjacent dust box by curved ducts 18. i y

The end vertical casings are designated by 17 and 17 .These are shorter than the others. The first of hem to the right 17-, is the intake end of the apparatus, and is provided with a box 19 which connects the apparatus with a duct, not shown, through which the cotton which is to be treated is introduced into the apparatus. The last of the vertical chambers to the left, 17 is the discharge end of the apparatus out'of which the treated cotton passes. This too is shown as provided with a connecting box 20.

' Inside of the vertical chambers, at prop erly spaced intervals, are sets of spring fingers. As these are all substantially alike, I will describe but one of them specifically. Referring to Figs. 2 and 3, it may be seen that 21 designates a transverse shaft upon which is mounted a frame 22 which carries a plurality of parallel rods or'fingers 23. These are made of thin spung metal and extend obliquely part way across the vertical channel. One end of the shaf t 21 is afiixed to a handle 24:, by means of which the angle of inclination of the fingers may be adjusted and their position maintained by pawls 25 on the handles engaging with fixed racks 26. ()ver each shaft and frame is a protecting plate or bracket 27. Opposite each set of fingers in the casings 17 is a glass covered port light through which the position and operation of the fingers may be observed and these are preferably removjfrble so that access to the fingers is provided or. V The apparatus is air-tight and the cotton to be treated is blown through it from end to end in an air current. The sets of fingers 23 project from opposite sides of thechannel through which the cotton passes and in opposite inclination so that the cotton is cleaned, opened and bloomed according to a method which has proved successful.

This apparatus is so constructed that the cotton is blown over the screens 13 at the bottom of adjacent chambers and the dirt substituted,

and trash, and heavier particles ofinatter Which it contained is thereby sifted out from it, and drops doWn intothe dust boxes. By placing the cleaning chambers in a vertical position there is no opportunity for eitherthe cotton or the extraneous matter,

after it has been removed therefrom, to lodge on the Walls of the chambers. By

means of this arrangement the number of sections installed may be changed at Will or a section may be removed and a new one thereby facilitating repairs. The dirt collects in thedust boxes from which it may be collected from time to time, and in the agitation attendant upon its removal, it has no tendency to fall into the cleaning chambers I What I claim is: I

1. A cotton cleaning apparatus built up "of a plurality of units, each comprislng a dust box ith a curved screen dividing the upper from the lower portion thereol", and

'a pair of vertical. casings having oppositely v p inclined sets of sprlng fingers thereln; and

connecting casings between the upper ends of adjacent casings of adjacert units.

2. A cotton cleanin apparatus built up of a plurality, of units, each comprising a dust box having a top constructed WithtWo Copies or this patent may be obtained for alining openings therein, and a vertical casing over each of the openings, a screen in eachbox curved from the farthest edges of said openings and forming the bottom of a continuous'air passage through said casings, said casings having therein oppositely inclined sets of spring fingers; andcurved connecting casings joining said units at the top of the vertical casings.

8. A cotton cleaning apparatus built up of a plurality of units, each comprising a dust box forming the base of the unit, each dust box having a top constructed with two rectangular openings therein, a semi-circular plate between the adjacent edges of said openings, a semi-circular screen between the opposite edges of said openings and concern tr1c with said plate, a glass covered port light above the screen and an air tight door below the screen, and a vertical casing over each of said openings, SillCl casings having therein oppositely inclined sets of spring fingers and a glass covered removable port,

five cents -each,'by addressing the Commissioner of Patents, Washingtoml). C.
